Choosing the Right LED
The most important step in selecting the right LED is to determine the type of fixture technology you have, either T8, T12, or T5.
To determine the type of tube you have, look for markings on the end of the bulb or measure the diameter of the tube, with T8 being one inch in diameter and T12 being 1 1/2 inch in diameter.
If this caught your attention, see: T12 Light Fixtures
If you have a T5 tube, it will be relatively small in diameter, about 5/8 of an inch.
Once you know the type of tube you have, you'll need to consider the kind of ballast, with T8 tubes using electronic ballasts and T12 tubes using magnetic ballasts.
Older fixtures are more likely to have magnetic ballasts, so it's worth checking the ballast to determine the type of LED you need.
There are three types of LED tube lighting to consider: Type A, Type B, and Type C.
Selecting the Right
To choose the right LED, you need to consider the type of fixture technology you have, either T8 or T12.
Determine the type of fixture technology you have by examining the markings on the end of the bulb, which will tell you if it's a T8 or T12. If you don't see markings, the size or diameter of the tube can give you a clue - T8 tubes are one inch in diameter, while T12 tubes are 1 1/2 inches in diameter.

If you have a relatively small tube, about 5/8 of an inch in diameter, it's likely a T5.
You'll also need to understand the type of ballast used in your fixture. T8 tubes usually use electronic ballasts, while T12 tubes have magnetic ballasts.
Older fixtures are more likely to have magnetic ballasts.
Once you know the type of tube and ballast, you can explore your replacement options.
Here are some common types of LED tubes and their characteristics:

Installation and Safety
To safely disconnect power before starting the replacement, turn off the circuit breaker that controls the light fixture and use a voltage tester to confirm that there is no power in the wiring before touching any components.
If you're comfortable working with electrical wiring, you can replace the fixture yourself, but if you're unsure or dealing with complex wiring, it's best to hire a licensed electrician to ensure safety and compliance with local electrical codes.
To remove the old fluorescent light fixture, start by removing the fluorescent tubes by rotating them out of the sockets, then take off the fixture cover or diffuser to access the internal wiring.
Here are the steps to safely remove the old fixture:
- Remove the fluorescent tubes by rotating them out of the sockets.
- Take off the fixture cover or diffuser to access the internal wiring.
- Disconnect the wiring by unscrewing the wire nuts connecting the fixture to the power source.
- Unscrew and remove the fixture from the ceiling or wall carefully.
Some LED light fixtures, like direct wire or ballast bypass LED tubes, can be installed by bypassing the ballast entirely, but this requires careful installation to ensure safety, as interacting with line voltage can cause potential hazards.
Safely Disconnect Power Before Starting
First, turn off the circuit breaker that controls the light fixture. This is a crucial step to prevent electrical shock or injury.
To confirm that there is no power in the wiring, use a voltage tester. This will ensure your safety while working with electrical components.

According to safety guidelines, you should never attempt to replace a fluorescent fixture with LED without first ensuring the power is off. This is a simple but essential step to avoid accidents.
Here's a simple checklist to follow:
- Turn off the circuit breaker that controls the light fixture.
- Use a voltage tester to confirm that there is no power in the wiring before touching any components.
Remember, safety should always be your top priority when working with electrical systems.

What to do with old items

So you've finished your installation project and now you're left with old items that need to be disposed of. Recycle properly, as many old items contain hazardous materials that need to be handled carefully.
Fluorescent fixtures and tubes are a great example - they contain mercury and must be disposed of at a hazardous waste recycling facility. Check with your local waste management for specific guidelines in your area.
You can also donate functional fixtures to organizations that accept used items for reuse. Some organizations may accept used fixtures, so it's worth looking into.
Here's a quick rundown of what to do with some common old items:
Remember to always follow local guidelines and regulations for disposing of hazardous materials.

LED tube lights have a longer lifespan than fluorescent tubes, with an average of 50,000 hours compared to 30,000 hours. This means you'll save on maintenance costs over time.
Some LED tubes qualify for financial incentives and rebates from utility companies, as well as business tax breaks. This is an added bonus to consider when making the switch.
If you choose to go with a ballast bypass/type B tube, you'll need to do some minor re-wiring of the fixture. This involves redirecting power from the ballast to the tombstone sockets, which can make your fixture even more energy efficient.
Here are some options to consider when replacing 4ft fluorescent tubes:
You can choose to go with one of these options or find your sweet spot somewhere in the middle.
Troubleshooting and Maintenance
Replacing fluorescent light fixtures with LED can be a straightforward process, but it's essential to follow some key steps to ensure a smooth transition.
First, turn off the power to the fixture at the electrical panel to avoid any accidents or injuries. Make sure to verify that the power is off using a non-contact voltage tester.
Measure the existing fixture's dimensions to ensure the new LED fixture will fit properly. This is crucial to avoid any costly mistakes or wasted materials.
When choosing a new LED fixture, consider the color temperature and lumen output to match your existing lighting scheme. This will help minimize any noticeable differences in lighting quality.
Check the wattage and voltage requirements of the new fixture to ensure compatibility with your electrical system. This is especially important if you're replacing a high-wattage fixture.
Take this opportunity to inspect and clean the existing electrical connections and wiring to prevent any future issues.

LED Lighting Basics
LED lighting is a game-changer for replacing fluorescent light fixtures. LED lights use significantly less energy than traditional lighting options, using up to 50% less power.
LEDs are also incredibly durable, lasting up to 50,000 hours or more, compared to fluorescent lights which typically last around 10,000 to 15,000 hours.
Tube Color Temperature
Color temperature is rated on a scale called Kelvin (K) and color usually ranges between 2400k to 6500k. A lower kelvin value will mean that the light output is going to be closer to an orange or “warm” or “soft” tint.
4000k T8 bulbs are known for being “cool white” with a color output that is close to clear metal halides. This color temperature is recommended for workspaces and offices.
A higher kelvin value means a bluer light output, with 5000+ kelvin T8’s being the “daylight” equivalent. Daylight color temperature will be recommended for any high-security areas, garage and display areas.
Tube Lighting Basics
When choosing LED tube lighting, you'll need to consider the type of LED that's best for your needs and budget. There are three main types: Type A, Type B, and Type C.
Type A LEDs, also known as ballast-compatible LEDs, are the easiest to install because they can use the same ballast as your existing fluorescent light. They're a popular choice due to their convenience, but they're also one of the more expensive options and have a lower energy efficiency.
Type B LEDs, or ballast-bypass LEDs, require the removal of the old ballast and get power directly from the line voltage. This can be a more complex installation, but it offers better reliability and energy efficiency.
Type C LEDs, or LEDs with an external driver, require rewiring and other modifications to your electrical fixture, but they offer the longest lifecycle, are the easiest on your energy bills, and provide the best dimming and lighting control.
Here's a brief summary of the pros and cons of each type:
Replacing 4ft fluorescent tubes with LED 4ft tube lights is a cost-effective option that uses 40% less energy and has a longer lifespan. This can save you money on maintenance costs and may even qualify you for rebates and financial incentives.
